The following affected performance (on a gross basis) during the reporting period: • Long exposure to securitized credit contributed to relative performance, as spreads tightened. • Curve positioning in the U.S., primarily underweight exposure to the front-end of the yield curve, contributed to relative performance, as yields rose. • Security selection of subordinated financials within investment grade corporate credit contributed to relative performance, as spreads tightened. • Long exposure to duration in Canada detracted from relative performance, as yields rose. • Underweight exposure to non-financial investment grade corporate credit detracted from relative performance, as spreads tightened. • Underweight exposure to the U.S. dollar detracted from relative performance, as the currency appreciated against a basket of major developed market currencies. |

Factors Affecting Performance [Text Block] | How did the Portfolio perform during the reporting period and what affected its performance? The following affected performance (on a gross basis) during the reporting period: • Underweight exposure to U.S. duration, specifically at the 7 year and 10 year part of the curve, contributed to relative performance, as interest rates rose. • Overweight exposure to commercial mortgage-backed securities ("CMBS") contributed to relative performance, as CMBS posted positive returns. • Overweight exposure to collateralized loan obligations contributed to relative performance, as spreads tightened. • A long bias to the Japanese yen versus the U.S. dollar detracted from relative performance, as the Japanese yen depreciated. • Long exposure to Australia duration, specifically at the 10 year part of the curve, detracted from relative performance, as interest rates rose. • Long exposure to United Kingdom duration, specifically at the 5 year part of the curve, detracted from relative performance, as interest rates rose. |

Factors Affecting Performance [Text Block] | How did the Portfolio perform during the reporting period and what affected its performance? The following affected performance (on a gross basis) during the reporting period: • Tactical curve positioning within U.S. interest rate strategies, particularly underweight exposure to the intermediate section of the curve in February and the first half of April 2024, as yields rose. • Long exposure to securitized credit contributed to relative performance, as spreads tightened. • Long exposure to investment grade corporate credit contributed to relative performance, as spreads tightened. • Long exposure to duration in the dollar bloc, primarily Australia, detracted from relative performance, as yields rose. • Selection across the coupon stack within agency mortgage-backed securities detracted from relative performance, as higher coupons outperformed lower coupons. • There were no other material detractors for this Portfolio. |

Factors Affecting Performance [Text Block] | How did the Portfolio perform during the reporting period and what affected its performance? The following affected performance (on a gross basis) during the reporting period: • Overweight exposure to U.S. breakeven inflation ("BEI") contributed to relative performance, as U.S. BEI moved higher. • Short exposure to eurozone interest rates contributed to relative performance, as eurozone interest rates broadly rose. • Exposure to agency mortgage-backed securities, including the associated carry, contributed to relative performance, as the sector posted positive returns. • Long exposure to Japanese BEI, contributed to relative performance, as Japanese BEI moved higher. • Overweight exposure to U.S. interest rates detracted from relative performance, as U.S. interest rates broadly rose. • Duration strategies in Japan, including short exposure to Japanese interest rate swap spreads, detracted from relative performance, as Japanese interest rate swap spreads tightened. • Long exposure to Australian interest rates, specifically in the last four months of the period, detracted from relative performance, as Australian interest rates broadly moved higher. |
